1, cervical spondylosis
Finger numbness is caused by cervical spondylosis.
Due to a series of pathological changes of cervical spondylosis, spinal nerve roots may be compressed, pulled and stimulated, resulting in numbness and swelling of fingers. It is characterized by numbness in the radial or ulnar side, or the fingers are close together, which may be accompanied by a decrease in grip strength.
Cervical spondylotic radiculopathy will have pain in neck and shoulder, neck, shoulder and back, head, upper limbs and hands. Most of the pain is dull pain, soreness, burning pain, or dull pain, or electric shock-like string pain. Numbness is often the same as the pain site, often accompanied by numbness, but numbness mostly occurs in fingers and forearms. Sensation of fingers and forearms decreases, and a few allergic areas appear, which is usually caused by stimulating the affected parts.
2. Transient ischemic attack
Patients with transient ischemic attack will also have symptoms of finger numbness.
Transient ischemic attack, also known as transient cerebral ischemia or "small stroke". Some elderly people often suffer from diseases such as hypertension and hyperlipidemia. Hypertension can cause vasospasm, hyperlipidemia can cause blood viscosity to increase, and blood flow is slow when sleeping at night. These factors will lead to transient cerebral ischemia and cause unilateral finger numbness.
Especially for multiple cerebral infarction, the symptoms are not obvious at first, and patients just feel numb in their hands and feet, which will not have much impact on their lives. If it is not found in the early stage, it will delay the best treatment opportunity, cause limb movement disorder and even paralysis.
Transient ischemic attack is a common and frequently-occurring disease in neurology, accounting for about 7% ~ 45% of ischemic cerebrovascular disease. After TIA 1 month, 4% ~ 8% patients have cerebral infarction.
3. Stroke
Stroke patients often have symptoms such as headache, dizziness, numbness of limbs and swelling of tongue. Finger hemp bloating is one of its symptoms, but it is usually accompanied by numbness in the arms and other parts.
4. Diabetes
Diabetes can lead to various complications. If the peripheral nerves are diseased, symptoms such as numbness of limbs and abnormal sensation will appear.
5. Rheumatoid arthritis
Finger hemp's swelling is one of its early manifestations, especially when it is accompanied by joint swelling and pain. If accompanied by scleroderma and finger skin, it may be scleroderma.
6. Carpal tunnel syndrome
Carpal tunnel stenosis, also known as carpal tunnel stenosis, refers to the thickening of transverse ligament of carpal tunnel, swelling of muscles in carpal tunnel due to wrist trauma, fracture, dislocation, sprain or wrist strain, tissue degeneration caused by blood stasis, or wrist bone degeneration and proliferation, which makes the inner circumference of carpal tunnel shrink, thus compressing the median nerve and causing numbness and weakness of fingers.
This disease often occurs in people who are engaged in professional handling, lifting, twisting and holding. The main symptoms of the disease are: numbness or tingling of the three fingers scratching the side, aggravated at night, painful awakening when sleeping, aggravated when the body temperature is high, and relieved after activities or throwing hands; In cold season, fingers are cold and cyanotic, fingers are not sensitive to movement, and thumb abduction muscle strength is poor; In severe cases, the thenar muscle atrophy of the affected side. Numbness and pain in thumb, food and middle finger, with a history of waking up at night, can be improved after waking up, which is called carpal tunnel syndrome.
7, mobile phone elbow
Elbow syndrome, commonly known as "mobile phone elbow" in recent years, is closely related to the frequent use of mobile phone products in people's daily work and life. Because when people answer the phone with their mobile phones, their elbows often bend over 90 degrees. Keeping talking posture for a long time will cause the ulnar nerve of elbow to be compressed or stretched, which will lead to the phenomenon that the ring finger and the little finger become "claw hands", or the thumb can't face the palm, the thumb and the index finger can't face each other, and the fingers can't be separated and combined.
Similarly, people who sleep with their arms resting on pillows will have their elbows twisted by more than 90 degrees. If this sleeping posture is maintained for several hours, it will also lead to the occurrence of "mobile phone elbow".
8. Peripheral neuritis
If the long-term digestion and absorption function is poor, malnutrition will cause peripheral neuritis caused by vitamin B 1 deficiency, and it will also cause numbness in the hands. At this time, just pay attention to adding some nutrition and supplementing vitamin B 1.
9. Acute alcoholism
For some people who often drink alcohol, if the palm feels numb, it means chronic alcoholism. If chronic alcoholism is not intervened in time, it will lead to dysfunction of various systems of the body, and even irreversible pathological damage, such as chronic gastroenteritis and ulcer, alcoholic myocarditis, fatty liver or cirrhosis, degeneration of the central nervous system or brain atrophy.
10, what should I do if I get to finger hemp?
1, finger numbness can not be treated symptomatically, but should be treated according to the cause. No matter what causes finger numbness, you should go to the hospital neurology department to check whether the nerve is damaged and what kind of stimulation is received.
2. If there are problems with the meridian, you need to do electromyography to further confirm the degree, scope and nature of nerve damage. If you have numbness of hands and feet caused by other reasons, you should go to other relevant departments for treatment.
3. The numbness of hands and feet caused by nerve injury should be treated with drugs or surgery according to the degree, scope and nature of nerve injury. Drug therapy is usually combined with acupuncture and physical therapy to promote its rapid recovery, while surgical treatment is to relieve the oppression and stimulation of nerves through surgery.
1 1, how to prevent finger numbness?
(1) Use both hands as much as possible.
According to the theory that the left brain dominates the right side of the body and the right brain dominates the left side of the body, it is always that one hand can only stimulate the brain that dominates the hand. People with left brain advantage should strengthen the use of left hand and left body, stimulate the potential of right brain, balance the relationship between left and right brain, and make it develop harmoniously. Therefore, people who like to use their right hands should exercise their left hands more, such as lifting things with their left hands, closing doors and windows, turning pages, practicing writing, drawing and working with their left hands. Left-handers should exercise their right hands.
(2) Cultivate the flexibility of fingers
Fingertips should be able to engage in some precise activities, such as assembling small plastic models, playing with small toys and sharpening pencils with knives.
(3) Enhance the flexibility of critical section.
This is conducive to improving the efficiency of the brain. Such as reaching your fingers, hanging your elbows to write and draw, knitting sweaters, etc.
(4) Exercise skin sensitivity
Insensitive skin touch means that the sensory center of the brain is dull, so always let your fingers receive hot and cold stimulation, such as washing your hands with cold water and hot water.
(5) finger movements are diversified.
Always monotonous methods will reduce the flexibility of fingers and limit the information transmission between the brain and fingers. Can carry out various forms of finger activities, if necessary, you can also use fitness balls to move your fingers.
12, prevention methods
(1) Increase the intake of protein from 0.8g/kg to 1g/kg ~ 1.5g/kg. Pay more attention to increasing the intake of milk, eggs and soy products.
(2) Increase the water intake, about 2000 ml per day. Even if you don't feel thirsty, drink water properly. Because water is one of the driving forces to increase appetite and regulate defecation.
(3) Relax dietary restrictions, and the calorie intake should reach at least 2000 calories/day.
(4) Prevent constipation, but avoid taking laxatives. Such as cistanche deserticola, dark plum and hemp seed. It has a unique effect on preventing and treating constipation in the elderly and enhancing physical fitness.
